Johnson Camp Trail and Grasshopper Road Loop

This loop is rated as difficult. While the Grasshopper Multi-Use Trail section, which makes up much of the ascent, is described as surprisingly manageable due to its consistent grade, the last three miles to Grasshopper Peak involve an almost 2,000-foot climb and are definitely steep. The return leg on the Johnson Camp Trail has a much shallower average grade, making it a less strenuous descent.

The loop typically starts and ends near the Big Trees Day Use Area in Humboldt Redwoods State Park. You'll find parking facilities available there.

The entire loop is approximately 17.3 kilometers (10.75 miles) long and generally takes around 5 hours to complete, depending on your pace and how long you spend enjoying the views.

You'll experience diverse forest scenery, transitioning from second-growth redwood uplands along Grasshopper Road to impressive old-growth redwood uplands on the Johnson Camp Trail. The Johnson Camp Trail is particularly scenic, with vibrant, brilliant green woods in the gullies. While forest views dominate much of the trail, the summit of Grasshopper Peak offers stellar 360-degree panoramic views, potentially including a glimpse of the ocean.

Absolutely! The primary highlight is Grasshopper Peak, which provides expansive, panoramic views in all directions. Approximately halfway up Grasshopper Mountain, you'll also find Johnson Trail Camp, a historic site with remnants of old cabins, a food locker, a spring-fed horse trough, and a vault toilet.

The terrain varies significantly. The ascent largely follows Grasshopper Road, which is a dirt road. In contrast, the Johnson Camp Trail on the descent features sections of singletrack trail. Be prepared for varying surfaces and a considerable uphill effort, especially as you approach Grasshopper Peak.

The Grasshopper Road section is a multi-use trail open to hikers, cyclists, and equestrians, which typically means dogs are allowed on leash. However, the Johnson Camp Trail is exclusively for hikers. Always check the latest regulations for Humboldt Redwoods State Park regarding dogs on specific trails to ensure compliance.

While specific seasonal conditions aren't detailed, generally, spring and fall offer the most pleasant hiking weather in redwood regions, with milder temperatures and less chance of extreme heat or heavy winter rains. Summer can be warm, especially on exposed sections, and winter may bring wet and muddy conditions.

Humboldt Redwoods State Park typically charges a day-use fee for vehicle entry. While specific hiking permits for this loop are generally not required, it's always a good idea to check the official California State Parks website for the most current information on fees and regulations before your visit.

Many hikers prefer to tackle the steeper ascent to Grasshopper Peak via Grasshopper Road first, getting the significant elevation gain out of the way. This allows for a more gradual and scenic descent on the Johnson Camp Trail, which is considered more visually rewarding.

Given its 'difficult' rating, significant distance (over 17 km), and substantial elevation gain (over 450 meters), this loop is generally not recommended for beginners or young children. It requires a good level of fitness and experience with longer, more challenging hikes.
